            Bug ID: 15753
           Summary: The sysdeps/powerpc/powerpc64/rtld-memset.c file is
                    compiled with wrong CPPFLAGS.
           Product: glibc
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: build
          Assignee: unassigned at sourceware dot org
          Reporter: brooks at gcc dot gnu.org

The sysdeps/powerpc/powerpc64/rtld-memset.c file is compiled into
rtld-memset.os with incorrect options -- notably, the rtld-CPPFLAGS variable is
not appended to the end of it.

This is causing a build breakage on my patched 2.17 build (using patches for
GCC 4.8 discussed at
http://sourceware.org/ml/libc-alpha/2013-07/msg00306.html); I'm not sure if
it's symptomatic or not on trunk.

The bug is that the set of pattern rules in sysd-rules is wrong, with the
%.os:%.c rule coming before the rtld-%.os:rtld-%.c rule.  Thus, the build of
rtld-memset.os matches the former rather than the latter, and gets built with
the wrong rule.

I have submitted a patch for this:
